However, there may be less Eider than it used to be, but there are still a lot of individuals. At least for a couple of years to go.... I visited the south coast a week ago, and during one morning around 20 000 eiders passed. Photographing migrating Eiders is pretty straight-forward, that is if you want portraits. To create something original is harder since so many people are doing the same thing. I had this in mind that morning.
We slept in the car, right at the beach, so I went down to photograph some landscape an hour before sunrise. The moon was up so I manage to capture some sea movement in moonlight as well as the pink sky. Then suddenly a flock of Eiders passed in the darkness. I realized that I had a chance to capture the migrating eiders in the reflected moonlight, which is pretty unique (at least I haven't seen it before).
Later that morning I also tried to capture the Eiders that passed right over head in a graphical shot with the wide angel lens.
